BINDER.

Application filed April 10, 1923.

To all who 1n it may 0092007721:

Be it known that l, EDWIN l Benson, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Binders, of whichthe following is a specification.

This invention relates to binders and has particular reference to oneadapted to enclose a replaceable filler such as a block of memorandasheets fastened together to itorm a tiller.

fill omcct of the invention is to provide iereby the filler may quicklyand easily be 'nserted into and removed from the hinder.

Another object is to provide means whereby the tiller is securely heldin place within the hinder although readily applicahle thereto andremovable therefrom.

A still further object to provide a tiller g ipping nien'iber whichpermits the achieve ent of the above named objects while being at thesame time economical to manufacture.

The invention is illustrated in the draw logs of which- Figure 1 is aperspective view or a hinder with filler inserted;

l igure 2 is a partial plan view of the hinderand filler showing thetiller gripping n ieinherg Figure 3 is a transverse the t ller and ignre4- is a partial perspective of the hinder showing the end o: the tillergripping member into which the filler is introsection througl'i grippingdevice and the binder;

It is of course clear that the form of the invention shown is only apreferred one of ma y in which it may be embodied for practic use andyet employ the ame inventive Serial No. 631,124.

In the preferred form shown in the drawings the invention relates to theuse of a binder back and cover members 11 and 12 between which aremovable filler or memoranda pad 13 is to be replaceably fastened. Inpractically every form in which they are supplied these pads are boundnear an edge such as 14 by binding members such as sta pics 1?.Therefore on the upper and lower surfaces of the pad or filler near thebound end times elements form a series of projections or notation-noes.This condition is taken advantage of in the following manner.

The filler is held to the back 10 by the engagement therewith 01 agripping member which in the term shown is a U-shaped channel plate 16having limbs 17 and 18 converging; orvtapering toward each other attheir outer ends. The plate 16 is fastened to the back 10 by anysuitable ans such as rivets 19. At one end each or the plates 17 and 18-are flared out as shown at 9.0 and 21 to facilitate the insertionot thefiller.

In order more eiiectively to avail myself of the projections on thetiller 13 whereby they may be made to assist in holding the filler inplace on the binder i prefer to hend back the outer edcjes of the limbs1'? and 18 as shown at and to form a rib or shoulder hack of which liethe projections on the tiller so that the tiller is ell-actively heldfrom slipping; out of the gripping element 16 and can only be removed byslipping the filler laterally out 01. the gripping element. Thisgripping member with the limbs 17 and 18 and ribs 22 and 23 is formed ofone piece of material so that the economy of its manufacture is greatlyenhanced.

I claim:

A. filler gripping member which includes a channel plate having limbs toengage a filler. and integrally formed right angular projections on theinner faces of the limbs projections on the bound end surfaces of thefiller to be directly engaged against the right angular projections onthe limbs.

In testimony whereof I afliX my signature.

EDWIN P. BENSON.
